Screen Printing: Infusing Versatility and Detail

Screen printing emerges as a porous printing method, seamlessly transferring words or symbols onto surfaces through controlled pressure application. Silicone-based printing ink, renowned for its non-toxicity and high adhesion, offers a canvas for diverse design expressions. While screen printing excels on flat surfaces, its adaptability on moderately curved surfaces extends possibilities through technological innovations and auxiliary fixtures. However, intricate designs with concave features pose challenges, with each color layer requiring individual printing and curing.

Pad Printing: Precision on Varied Surfaces

Pad printing emerges as a specialized method capable of imprinting text, graphics, and images on irregular surfaces with precision. Its versatility extends to various surface profiles, from planes to spheres, cylinders, and irregular shapes. Despite its limitations in comprehensive coverage and alignment precision, pad printing, when combined with screen printing, offers a hybrid solution meeting diverse aesthetic demands. The resulting graphics exhibit a subtle three-dimensional effect, enhancing tactile experiences.

Laser Etching: Illuminating Functionality

Laser etching harnesses the light-transmitting property of silicone to engrave patterns or symbols on surfaces, achieving opaque or translucent effects. This process not only enhances visual appeal but also aids nighttime usability, facilitating easy identification of operational panels. Laser engraving further refines designs by removing surface paint layers, revealing the original silicone material color and creating light-transmitting keys for enhanced functionality.

Epoxy Coating: Transformative and Protective

Epoxy coating transforms silicone surfaces, imparting a sealed, insulative, and glossy finish akin to plastic. This method offers a durable top coat, protecting printed graphics while enhancing abrasion resistance. With a minimum thickness of 0.5-0.7mm, epoxy coating elevates the visual and tactile qualities of silicone products, ensuring longevity and aesthetic appeal.

Spray Painting: Customizing Appearance and Protection

Spray painting offers a versatile surface treatment, allowing precise application of protective coatings to enhance tactility and abrasion resistance. Colored paint spraying introduces visual transformations, while silicone and PU coatings provide soft-touch textures and additional protection against dust and abrasion. PU spraying, in particular, caters to matte glaze requirements, enhancing surface smoothness and durability.
